SPECIFICATION forming part of Letters Patent No. 594,781, dated November 30, 1897.

Application filed April 3, 1897. Serial No. 630,612. (No model.)

To all whom it may concern.-

Be it known that We, CHARLES S. DOLLEY, JOHN G. REHFUSS, and JAMES HUNT, citizens of the United States, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvements in Bottle-Filling Machines; and we do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.

This invention relates to certain new and useful improvements in apparatus for bottling liquids, and it is especially adapted for use in connection with that class of fillers which are adapted to be operated by what is known as the vacuum process.

The invention has for its object the general improvement upon the construction and to render more effective the operation of bottling machinery of this character.

The invention has for its more immediate object the provision of a simple, positivelyoperated, and inexpensive machine in which provision is had for the filling of bottles of varying heights and in the provision of apparatus connected with a vacuum-chamber and source of liquid-supply whereby the movement of a single lever will effect the exhaustion of the air from the bottle to be filled and the filling of the bottle.

A further essential object of the invention resides in the provision, in connection with the machine, of an expansion cylinder or chamber adapted to receive the surplus gas contained within the bottle, thereby permitting the bottle to be completely filled.

To these ends and to such others as the invention may pertain the same consists in the novel construction and in the peculiar arrangement, combination, and adaptation of parts, all as more fully hereinafter described, shown in the accompanying drawings, and then specifically defined in the appended claims.

The invention is clearly illustrated in the accompanying drawings, which, with the letters of reference marked thereon, form a part of this specification, likeletters indicating the same parts throughout the several views, and in which drawings- Figure 1 is a side elevation of a bottlingmachine embodying our invention. Fig. 2 is a front view, upon an enlarged scale, of the upper portion, of' the machine, partly in section, the section being taken upon line 2 2 of Fig. 3. Fig. 3 is an enlarged side elevation of the upper portion of the device, showing the vacuum and filling or supply ports. Fig. 4 is a transverse section upon line 4 4 of Fig. 2. Fig. 5 is a section upon the line 5 5 of Fig. 4:. Fig. 6 is a side view of the lower portion of the machine, the same being the reverse side of that shown in Fig. 1. Fig. 7 is an enlarged detail of the spring-controlled adjusting mechanism which compensates for the difference in the heights of bottles to be corked. Fig. 8 is a perspective view, upon an enlarged scale, of the lower end of the plunger.

Reference now being had to the details of the drawings by letter, A designates a standard, which in the present instance is shown cylindrical in form and secured to a suitable base B. At its upper end the said standard A is provided with an arm A extending upward and slightly outward from the standard, and pivoted to the upper end of said arm is one end of an arm A which arm A at its opposite end is pivotally connected to a link A which link at its lower end is pivotally connected to the upper end of the plunger O.

D is a pedal pivoted within ears D at the lower end of the standard, and the said pedalarm D is connected with the lever A by means of a rod D ,which extends upward through the interior of the standard and is pivotally connected at the center of the arm A as shown at D In order to automatically hold the pedal normally in a raised position, as shown in Fig. 1, a spiral spring D is provided,which spring encircles the upper portion of the rod D and has bearings provided at its ends, as shown.

E is a bracket-shelf which is carried by a plate E, which plate is vertically movable within suitable guides E upon the front face of the standard A. This shelf E is adapted to receive the bottle to be filled and is accordingly provided with a depression within which the bottle to be filled is placed.

In order to effect an upward or downward movement of the shelf E, the following mechanism is provided.

F is a segmental gear pivoted at F within ears provided uponv the standard A.

F is a cam pivoted between arms F upon the front side of the standard A, and keyed to or integral with the said cam is a pinion F which is adapted to mesh with the teeth of the segment-gear F.

G is a link pivotally connected at its upper end with the plate E by means of a pin e passed through a vertical slot e provided in said plate. The lower end of the link G is provided with an opening within which is seated the pintle G of the member G the pintle G being provided with laterally-extending lugs g, which are contained within an elongated opening G At the upper end of the pintle G a spiral spring G is provided, the tension of which spring serves to normally hold the member G downward at the extreme limit of its throw. Pivoted within the bifurcations G at the lower end of the member G is a friction-roller G which bears upon the periphery of the cam F 11 is a casting provided at one of its sides with a cut-away portion 11 to receive the cork. The lower portion 11" of the said casting H is provided with a rubber cushion Y, which is adapted to inclose the upperend of the bottle, when by a downward pressure of the pedal the shelf with the bottle thereon is forced upward.

I is a casting or head-block within which are provided the vacuum and supply ports and the connections between the same and the ports leading to the bottle.

J is a hermetically-sealed expansion-cylinder from which in the operation of the machine the air may be exhausted for a purpose which will hereinafter appear.

J is a pipe leading to the vacuum-chamber, and J a pipe leading to the source of supply. Upon reference to Fig. 3 it will be seen that the said vacuum and filling pipes J and J respectively enter the head-block I and that both of the said ports communicate directly with a common chamber K which has direct connection with the port leading to the bottle to be filled. In order to provide for the controlling of the inlets or ports leading from the vacuum and from the source of liquidsupply at will, we provide a shaft K, which is provided with a valve K the said Valve being normally seated by means of a spiral spring K surrounding the valve-stem within the chamber K and the said valve is adapted to be opened against the tension of the said spring by pressure applied to the extreme end or point K of the shaft. It will be observed that b oth the vacuum and the liquidsupply ports are alike, and each being controlled by a spring-actuated stem K, carrying a valve controlling the port which communicates with the common chamber K the two valve-stems K being upon the same horizontal plane and separated a short distance.

L is an opcrating-handle which is pivoted at its end L between the projecting ends of the valve-stems K and is provided at its pivoted end with laterally-extending arms L, which arms are adapted to contact with the valve-stems K, controlling the vacuum and liquid-supplyports upon moving the lever from one side to the other, so as to exhaust the air from the bottle or cause the liquid to enter the same, as desired.

M is a small passage or port connecting the common chamber K with the expansion-cylinder J within which chamber K is seated a plunger J as shown. In order to stop the downward movement of the plunger 0 at the proper point to permit the surplus gas to leave the bottle before the cork is seated, as will hereinafter appear, an angle-lever N, one arm of which is provided with an operatinghandle N is pivoted at its angle between ears N provided for the purpose upon the end of the head-block II.

The operation of the machine is as follows: The bottle to be filled is placed upon the vertically-movable shelf E. The pedal D is depressed and the shelf is raised by the rod G, the friction-wheel G at the lower end of said rod traveling upon the cam F and the said cam being rotated by the engagement of the pinion F with the segmental gear F. Simultaneously with the upward movement of the shelf the plunger 0 is forced downward through the connections, consisting of the rod D", lever A and link A existing between t-he pedal and plunger. The plunger in its downward movement forces the cork, which has previously been placed in the opening H downward within the casting H, the said downward movement of the plunger being stopped by the arm N of the angle-lever N the operatingarm of which has been thrown upward, so as to throw the arm N against the plunger-rod O,where it is brought in contact with the link A. The cork when forced downward to this point closes the opening in the upper end of the casting H; but a slight space intervenes between the bottle-neck and the chamber K By throwing the operating-lever to the right the arm L is brought into contact with the valvestem K, controlling the vacuum-port, and the air is at once withdrawn. from the bottle. The operator then throws the lever L to the left, thus opening the port leading to the source of liquid-supply, and the bottle is filled. The expulsion of the gas from the charged liquid during the filling process causes the gas to pass through the port M into the hermeticallysealed cylinder J where it drives the piston in said cylinder upward, thereby relieving the pressure within the bottle sufficiently to permit the bottle to be filled, as will be readily understood from the foregoing description, and as the gas enters the said cylinder J X the piston contained therein is forced upward. The bottle having been thus completely filled, the lever N is forced downward, thus throwing the arm N away from the plunger-rod and permitting the plunger to be forced downward. A slight movement upon the pedal will then suffice to seat the cork within the bottle. The cork is then clamped or secured in place. A slight upward movement upon the pedal at this point will cause the plunger to slightly rise from the cork, thus permitting the removal of the bottle from the machine, a furtheru'p ward movement restoring the parts to their original positions.

Having thus described our invention, what we claim to be new, and desire to secure by Letters Patent, is

1. In a bottle-filling machine, an upright, a treadle pivoted thereon, a toothed segment also pivoted upon the standard and connected to the treadlc, a pinion with which the segment engages, and a cam, the pinion and the cam being connected so as to rotate together; combined with a pivoted arm, and a rod for moving the bottle-support vertically, substantially as shown.
